查询词典 photons

The results showed that most of the photons are absorbed after multi-layered tissue scatterings with about 7.3 percent reflectance (specular reflectance and diffuse reflectance ) from epidermis.Based on the knowledge of optical parameters of biological tissues, we simulated the light distribution and propagation with different types of incidence.

选定生物组织光学特性参数的前提下，结合文中介绍的卷积理论，模了各种类型的光束在生物组织中的传播与分布情况，并且给出了生物漫反射光分布的特点，为实验中对光和生物组织相互作用后的漫射光提供参考。

The scintillators absorb the X-rays and convert them into visible light photons that then pass onto the photodiode array.

这个闪烁物可以吸收 X 射线并将他转化成可见光光子，然后进入光电二极管阵列。

Charge comparison method used to discriminate photons and neutrons in liquid scintillators.

陈宇， 王子敬，毛泽普，等，电荷比较法测量液体闪烁体n，γ分辨性能。

The last big question on Hollis's research agenda -- whether the cells will reset after having fired -- may not even matter in the group's latest vision for a handheld biosensor: a proposed optical-electronic box would read the photons emitted by a swappable and disposable biosensor chip, which would cost just a few dollars.

在霍利斯的研究日程表上，最后一个大问题在于细胞在发光后是否能够重新设定，按照研究小组最近对手动探测仪的设想，这个问题可能并不太重要：人们拟利用光电盒读取可交换的一次性生物探测芯片发出的光子，而光电盒只需要花费几美元。

However, MC method is timeconsuming due to the calculations of a large number of photons propagation in tissues.

为了得到足够的仿真精度，MC方法通常需要仿真大量光子包在生物组织中的传输过程，这个过程是相当耗时的。

Quantum cryptography provides confidential communication by sending streams of photons their measurement by the legitimate parties and the subsequent post-processing of the measurement data the result is a cryptic key made up of identical random "bit strings".

量子密码提供保密通信发送的光子流-他们测量的合法政党和随后的后处理测量数据-结果是一个秘密的关键了相同的随机&位串&。

All relevant experiments including photoelectric effect and Compton scattering just show that light manifests as one and other photons in its interacting with matter,but does not so in its free propagating.

以光电效应和康普顿散射为代表的一切有关实验证明了的都是光在与物质相互作用时以光子的形式出现，并没有证明光在传播中以光子流的形式存在。

In Doppler effect, Gravitational red shift and Compton effect as it changes frequency the photons (including γphoton ) always abide by constant principle of light speed ,which proved that the photon has zero mass.

在多普勒效应，重力红移和康普顿效应中，光子在频率发生变化时总是遵守光速不变原理，由此证明了光子具有零质量。

These facts conflicted with current theory and were not explained until 1905, when Einstein produced his quantitative law and developed the theory of quanta of light or photons, which was verified much later by Millikan.

此后，莱纳德又继续拓展赫兹关于光电效应的研究，他分析了在高真空环境下光电效应的特性和本质，证明了当紫外线照射在金属上时，会使电子从金属表面逸出，并在真空中传播，电子在电场中被加速或减速，电子轨迹在磁场中改变。通过精确的实验，他证明发射的电子数量正比于入射光所带的能量，而电子的速度，或者说它们的动能，却与入射光能量无关，当入射光的波长减小时，电子速度增大。这个事实与当时的理论是相冲突的，经典物理学无法解释莱纳德的光电效应实验结果。
